Transporting a refrigerator is a responsible process, especially if the equipment was transported in a horizontal position. Many users are wondering: how long should a refrigerator sit after being transported on its sideto avoid breakdowns when turned on for the first time. The answer depends on the type of compressor, model, ambient temperature and even the brand of oil in the system.
In this article we will analyze the physical processes occurring inside the refrigeration unit when tilted, we will provide precise recommendations on settling time for different types of equipment (inverter, linear compressors, systems No Frost), and we will also give step-by-step instructions for preparing for the first start. We will pay special attention to models with digital electronics - they cannot be turned on immediately even after vertical transportation!
Why you can’t turn on the refrigerator immediately after transportation on its side
The main reason is risk of compressor water hammer. When the refrigerator tilts, oil from the compressor crankcase enters the refrigerant (freon) circuit. If you turn on the equipment immediately, the oil can:
- 🔌 Block the capillary tube - this will lead to overheating of the compressor and its failure.
- 💧 Mix with the refrigerant and form foam, which will disrupt heat exchange in the condenser.
- 🔊 Causing a characteristic knocking and vibration during startup is a sign that the oil has not had time to drain back.
In modern models (for example, Samsung RB30A3200SA or LG GA-B409SQDL) are used inverter compressors, which are more sensitive to oil starvation. Even short-term operation without lubrication can lead to jamming of the piston.
⚠️ Attention: If the refrigerator was transported at an angle of more than 40° (for example, in the trunk of a car), the settling time increases by 30–50%!
How many hours The refrigerator should stand on its side after transportation
General rule: minimum 4-6 hours for household models with a linear compressor. However, the exact time depends on several factors:
| Refrigerator type | Room temperature | Minimum settling time | Recommended time |
|---|---|---|---|
| Linear compressor (for example, Atlant MXM 1705) | 18–25°C | 4 hours | 6–8 hours |
| Inverter compressor (Samsung RB37A5200) | 18–25°C | 8 hours | 12–16 hours |
| System No Frost (for example, Bosch KGE39AW25R) | 10–17°C | 6 hours | 10–12 hours |
| Industrial refrigerators (for example, Lieberr GKes 1460) | 5–30°C | 12 hours | 24 hours |
For models with two compressors (for example, Haier C2F636CWG), the settling time increases by 2-3 hours, since the oil should be evenly distributed in both circuits.
What to do if the refrigerator was transported in winter
When transporting in the cold season (below +5°C), an additional risk arises: thickening. oil. The viscosity of the lubricant increases and it takes more time to drain into the compressor crankcase.
Recommendations for winter transportation:
- ❄️ Give to the refrigerator warm to room temperature (at least 2 hours) before settling.
- ⏳ Increase the settling time by 30–50% (for example, instead of 6 hours - 8–9 hours).
- 🔋 Do not connect to the network if there is condensation on the case - this is a sign that the internal parts have not yet warmed up.
⚠️ Attention: If the refrigerator was transported at a temperature below -10°C, the settling time should not be less than 18–24 hours, even for models with a linear compressor!
Step-by-step instructions: how to properly prepare the refrigerator for use. first start
To avoid damage, follow this algorithm:
- Install the refrigerator on a flat surface. Use a level to check that there are no distortions. The legs should be adjusted so that the equipment does not swing.
- Clean the internal surfaces. Wipe the chambers a weak solution of soda (1 tablespoon per 1 liter of water) and dry.
- Check the drainage hole. It must be clean - clogged drainage can lead to water accumulation in the lower part.
- Connect to the network through a surge protector. This will protect the electronics from power surges when first started.
- Start the refrigerator in the "Vacation" mode (if available). This is a gentle mode for the first start.

For models with display (for example, LG Instaview Door-in-Door) it is recommended to reset the settings before turning on for the first time to factory settings. This can be done through the menu: Settings → Support → Reset.
What happens if you turn on the refrigerator ahead of time
The consequences of premature startup depend on the degree of violation of the rules:
- 🔥 Overheating of the compressor —the most common problem. Signs: the refrigerator runs without stopping, the body is hot, but it is not cold inside.
- 💥 Hydraulic hammer —oil enters the compressor cylinder and blocks the piston. Characteristic sound: a loud knocking sound when starting.
- ❄️ Improper distribution of refrigerant —one of the chambers is not cooled, and the other is freezing.
- 🔌 Electronics failure —in models with a display, the firmware may go wrong and errors may appear
E1,FFordH.
If after turning on you hear uncharacteristic sounds (grinding, loud humming, clicking), immediately unplug the plug and let the refrigerator sit for another 12-24 hours.
Signs of breakdown after incorrect starting
If the refrigerator turns on, but turns off after 5-10 seconds, this is a sign of overheating protection. In 80% of cases, the problem is solved by repeated settling within 24 hours. If the situation repeats, replacement is required. compressor.
Features for refrigerators with the No Frost system
Models with No Frost (for example, Indesit DF 4200 W or BEKO GNE 114620 X) have an additional fan and evaporator located behind the back wall When transported on its side. oil can get into the air duct system, which will lead to:
- 🌀 Slow cooling — the fan will drive warm air.
- 🔇 Increased noise —the fan blades can touch the oil.
- ❄️ Icing of the evaporator - due to impaired refrigerant circulation.
For such models it is recommended:
- Leave the refrigerator for 2-3 hours longer than indicated in the instructions.
- After turning on, check the operation of the fan - it should rotate smoothly, without extraneous sounds.
- For the first 12 hours, do not load the chambers with food more than 30%.
Frequent errors during transportation and settling
Even experienced users sometimes make mistakes that lead to breakdowns. Here are the most common:
- 🚛 Transportation in a lying position without fixing. If the refrigerator “bounced” in the back, oil could splash all over the circuit.
- ⏱️ Insufficient settling time. Particularly critical for inverter models - they can fail even with minimal oil fasting.
- 🔌 Connect to the network immediately after delivery. Even if the refrigerator was standing vertically, it needs 1-2 hours to acclimatize.
- 🧊 Loading products immediately after switching on. The compressor must first enter operating mode.
If you suspect that the refrigerator was transported in violation (for example, it was dropped or strongly shaken), the settling time should be increased to 24 hours, regardless of the model.
⚠️ Attention: In the instructions of some brands (for example, Liebherr) it is indicated that refrigerators with inverter compressors cannot be transported horizontally at all. In such cases, vertical transportation or the use of special transport fastenings is required.
FAQ: Answers to frequently asked questions
Is it possible to speed up the settling process, for example, by tilting the refrigerator in the other direction?
No, this will only aggravate the situation. The oil should drain naturally under the influence of gravity. Any manipulations (tilts, shaking) can lead to oil getting into the refrigerant circuit.
What to do if the refrigerator has already been turned on ahead of time and it does not cool?
Unplug it from the outlet and let it stand for 12-24 hours. If the problem persists after turning it back on, call a technician - there may be a water hammer or a blockage in the capillary tube.
Does it need to stand for the refrigerator if it was transported vertically?
Yes, but the time can be reduced to 1-2 hours. This is necessary to stabilize the pressure in the system and warm the oil to operating temperature.
How to check that the oil has flowed back into the compressor?
Gently rock the refrigerator back and forth. If you can't hear fluid pouring inside, the oil has most likely returned to the crankcase. You can also slightly tilt the equipment back - if the compressor does not “gurgle”, everything is in order.
Is it possible to transport a refrigerator on its side if it is new and has not been turned on yet?
Yes, but the rules for settling remain the same. In new refrigerators, oil is already poured into the compressor, and when tilted, it also enters the system. The exception is models with transport bolts (for example, Siemens iQ500), which fix the compressor.
